There are 80 people in line to get a famous soccer player's autograph. But she only has time to sign 50. Each person in line is allowed to get only one autograph. What is the quantity of autographs supplied?

hi my dude or dudette

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
